An apparatus and method for lossless run-length data encoding is disclosed. In the first stage of the method, an input data sequence is transformed without increasing its volume in order to obtain long sequences of identical digits. In the second stage, every such sequence is replaced with a unique shorter sequence. The compressed data is decoded performing corresponding inverse operations. The method is very efficient for compression of some classes of digital images with long sequences of the same number, such as graphics, texts, signatures, and fingerprints.
